I have not implemented a function hook for a post-processing function,
since Fox is built to be able to process posting to multiple pages,
and it is a little hard to determine when a post-processing function
should be triggered.

But you could use the global variable $IsPagePosted, which is set to
true if  a page is posted, and use the php function
register_shutdown_function, which lets you run a custom function
once pmwiki is finished. You could put all this into your filter
function. For instance like this in the FoxFilter function:

   global $IsPagePosted;
   if ($IsPagePosted)
       register_shutdown_function('MyCustomPostProcessFunction', $pagename);

Hope this helps a bit.
